This inif'ention relates to printing' telcgraph systems et the in whicha single t1'a1i:5ii'iisf,-:i n circuit between the transn'litter and thereceiver (or receivers) controls all the operations et the latter,including` setting ot the ty .ve Wheel or type-carrier, making' the impt d eltecting spacing' between iinprints. in systems et this class thetype or printing' charm Yers are arranged in two rows on the type wheel,which is rotated step by under the control ot 'the usual electro- Yescapement t bring the desired to jthe priiiting' position, but in ormeither row at will one or ments ot the printin couple must be To makethe shitt it is necessary to rotate the type Wheel to a shift positionand make what is virtu ally an idle. stroke ot tlf-e p' ating elements.For example, supetters ot the alphabet are in one row pe Wheel and thenumerals, iracpiu'ictuation marks 'in the other, and desired to printthe letter G, toliL-l Y; tilde E loweil by a n'. faber, say 5, thenanother letter.

this operation the type Wheel is rotated step by sten until C p lf is atthe impression point. The letter is then printed, atter Which the typewheel is to the suitt position. An idle stroke is then made (or a periodis printed type has a period the shi'lftposition), by proper cooperationwith the printaten shifts the latter to the other or ron' oil type. The'wheel is new rotatefjl to bring' 5 to the printing' position, '-iprintis made. then in order to shift back Lie letters rouv the type Wheelmust be again rotated the shitt position and anothei die stroke.

Upon ection it will be seen that rotati 'type Wheel to the shiittposition and man 'gj an idle stroke requires a certain amount ot time,and that this time is lost since soi/'ul letter or nun'ieral printed inthe operation. ,in usine' the system to les on stock oxclanges or otherei:- rlianzfrs the loss ot time is sometimes very ions. as when theuiarkotf7 is active.

serial No. 144,230.

in which the shitt from one row ol' type to another can be effected atany position of the type Wheel, thereby effecting' a marked increase inspeed ot operation. In tact, With the preferred embodin'ient hereinafterde sci'il. ed We have been able to increase the speed much as 'forty percent, depending somewhat, et course, upon the skill of the sending;`operator. Another object is to provide tor the purpose statedinstrumentalities which can be added to or incorporated in exiting;systems at reasonable expense. A Yfurther object is to provide shiftmechanism and shitt controlling mechanism Which is not lin ilcd to usein one-ivire systems. To these and other ends the invention comprisesthe novel iteatures and combinations hereinafter described.

lfn carrying` out our invention in the prer red manner We make use of aprinciple which has been employed 'for other purposes in printing;telegraphs, namely, variation 'in the strength ot the current used tocontrol. or

@were this principle has not heretofore been employed to elicct theshitt in a one-Wire tape-printer or ticker system. By such n'ieans, Weare able to do with a single transri circuit what has hitherto requiredt two in such. systems, and We thus obhe desired increase ot speedWithout to the large expense of a second Wired the various forms inwhich the invention can be euibodied We have selected tor speci'linllustration and description herein the one which at the present time Weconsider the most etllective. This for n is based on a Widely usedsystem in which the current sent over the transmssion circuit is otalternating` polarity, causing` corresponding' alternations in thepolarity ot the electromagnets which control the type Wheel. escapementoit the recei Ver thereby causing; or permitting' the type wheel torotate step by step. 1When the dcsirod chara-.ifter has thus beenbrought to the impression point the linal current impulse is prolonged,ei abling such impulse to energize a magnet ot longer time-constant,known generally the printing' or press magnet. 'lhe latter, thusenergized, actuates the platen and spaces the tape along one step. lnaccordance with our invention as applied in the preterred manner to thesystem referred to, n'eak current causes imprints to be made from onerow et type, say the row containnier-1l euses lo operate llie pres zuidshi'iil ningneis en local eireuils inner the control ol relays in vhetransmission line.
